Select a Page or Book and then pick “Recent Changes” from the Upper Right Menu.

I find the most effective and useful list is the Old Revisions List which is more complete, for a given page. Select a Page and then pick “Old Revisions” from the Right Margin Menu.

Once “Old Revisons” is selected a good list appears showing each time the page was “Saved”.

You can roll back to a previous page, first by selection of one of the old revisions (use browser page back if you have not picked the right page). Then go to the bottom and pick “Save” this will re-establish that old revision version of the page as the current version.

It is possible to “Restore” an accidentally deleted page from the “Attic”. This is done by Administrators. So make a request to one of the administrators.

First find the deletion and deleted page under “Recent Changes”, click on it. Then you can use “Old Revisions” to find the correct version.
